4th International Conference on Ontologies and Knowledge Graphs 2025 ICOKG 2025 is a research-oriented conference on knowledge graphs, natural language processing, ontologies and other related topics.

In this 4th edition will be held in the Departamento de Sistemas, Universidad Autonoma Metropolitana, Azcapotzalco in collaboration with the Faculty of Computer Sciences of the Benemerita Universidad Autonoma de Puebla, Puebla, Mexico. However, some magistral conference will be virtual in some platform for online conferences.

ICOKG 2025 aims to be an open forum for communication between students and researchers who carry out initial, intermediate and final research on topics in graph theory, knowledge graphs, semantic web, natural language processing, data science and conference-related topics.

The papers will be reviewed following the double-blind approach. Papers should not include information that clearly identifies the authors, nor citations. The original accepted works will be published as chapters of a book. All papers accepted must be written in Spanish

The papers with the highest evaluations will be invited to participate in a special issue, which will be submitted to a single-blind review process, for publication in the IJCOPI journal and the Contaduría y Administración journal. All papers accepted must be written in English.
